【摘要】 目的:探讨针刺“内听宫”穴治疗突发性耳聋的机理。方法:使用诱发电位仪测定正常组、突聋组的ABR,观察针刺“内听宫”穴前后ABR的变化。结果:针刺正常耳“内听宫”穴,针刺前后ABR的Ⅰ波、Ⅴ波潜伏期以及Ⅰ-Ⅴ波间期无显著性变化(P>0.05);而针刺突聋耳“内听宫”穴后,其ABR波形分化明显清晰,Ⅰ波、Ⅲ波、Ⅴ波均出现,且重复性好,Ⅰ波、Ⅴ波潜伏期缩短(P<0.05)。结论:针刺“内听宫”穴能提高突聋耳耳蜗听神经以及外侧丘系桥脑的兴奋性和传导性,但对正常耳无影响。该穴位可用于治疗突发性耳聋。更多还原

【Abstract】 Objective To study on the mechanism of acupuncture at point "Neitinggong" for treatment of sudden deafness. Methods Changes of auditory evoked potentials of the brain stem were determined in the normal group and the sudden deafness group before and after acupuncture at point "Neitinggong". Results After treatment, in the normal ears, the latencies of wave Ⅰ and wave Ⅴ and the intermission of Ⅰ-Ⅴ did not change significantly (P>0.05); and in the sudden deafness ears, the wave shapes of the evoked potentials become obviously clear with wave Ⅰ , Ⅲ and Ⅴ appeared and the latencies of Ⅰ , V shortened (P<0.05). Conclusion Acupuncture at "Neitinggong" can increase the excitability and conductivity of the cochlea auditory nerve and the pons of lateral lemniscus in the sudden deafness ears, but not in the normal ears. It is suggested that point "Neitinggong" can be used for treatment of sudden deafness.更多还原
